I stumbled accross two really helpful projects which convert the Latin Letters or Numbers into Braille.
Unfortunately I can't read/feel them but I thought it might be useful.

Instructions:

• Download Openscad
• Install it
• Download the file “braille.scad”
• Open it
• Enter the desired text
  • for instance text = ["^Hello Makerworld!","This is Braille"];
• Render it and export it as STL/OBJ etc.
• Import it in your slicer and print it.
  The Sample file has two text lines, each line is a separate object in that array

Happy printing,

let's reduce some barriers!
